Sorting references
You can choose how to sort your references under Sort by in the Display options menu.
Results are automatically sorted to Best Match. This uses an algorithm which counts the number of times that your search terms appear in a record. Other criteria applied in order to rank the order of results in Best Match include publication type and year.
This feature is intended to help you find highly relevant papers quickly and is useful for quick scoping searches.
If you are doing a structured search, for example using the MeSH feature and Advanced Search to combine terms, we would recommend you sort by either publication date or most recent. This is because the Best Match algorithm is constantly changing and it is not possible to replicate a set of search results generated by using this feature. If you have used search operators such as AND and OR then these are also not fully applied, and you can not know exactly how your search has been carried out.
